SPRAYER.

SPECIFICATION forming part of Letters Patent No. 563,829, dated July 14, 1896.

Application filed March 10, 1896. Serial No, 582,531. (No model.)

to meisten or dampen before handling when dry, so the leaves will not break or tea-r, but it is equally applicable, of course,lfor spraying flowers and plants or for dampening cloth or clothing, if desired.

The object of the invention is to construct a simple, convenient, and cheap portable utensil that will be light and strong and that can he operated to throw a veutT iine sprax7 for a considerable length of time.

To this end the invention resides in a shell containing an air chamber or receiver and a liquid chamber or tank, which chambers are connected together by a duct arranged in a peculiar manner, said shell being provided at the upper end with a controlling-cock and a spraying-nozzle and at the lower end with an inlet-duet containing a stop-cock and a cheekvalve, the latter duct being connected with the hollow cylindrical handle shell or tube, which is provided with a piston that can be reciprocated to generate air-pressure, all the parts being combined and arranged as more particularlyhereinafter described, and pointed out in the claims.

Referring to' the accompanying' drawings, Figure 'l is a central longitudinal section of the utensil. Fig. is a detail enlarged section of the duct leading from the handle-tube to the air-receiver. Fig. 3 is a viewof the bottoni of the piston, and Fig. l is a view of the upper side of the sprayin g-nozzle.

ln the views, l indicates a cylindrical shell that is made of sheet metal of proper Strength and durability, with dome or crown ends. This shell provides the air chamber or receiver and the ends are curved outward to insure sufficient strength. To the bottom of this shell is secured a sheet-metal ring or base 2, so that the shell will stand upright. Upon the top of this air-chamber shell is secured a small cylindrical shell 3 of the same diameter.

This upper shell provides the liquid chamber or tank, and the lower end `is flanged and secured to the top of the air-chamber shell in any suitable manner, and. a ban d l is put about this joint between the two parts of the shell to give strength and make the parts practically into one shell with the two chambers. The top of the liquid-tank is domed or crowned outward and provided with a threaded opening at the center.

The opening in the top of the upper shell or liquid-tank is threaded, and screwed therein isa perforated cap or stopper 5. This cap has a tube G secured. to it so that when the cap is screwed tightly to place the tube will extend down to the lower outer corner of the liquidchamber in the top shell. Then the cap is removed, any desired liquid mixture or pure water can be poured into the tank and all of it can be sprayed out when the utensil is being used, because this outlet-tube leads to such a position that if the sprayer is not held upright, but inclined forward, so that the water runs to the lower front edge, the end of the outlet-tube will be immersed until the liquid is all sprayed out.

To the cap is secured a cock 7,that may be opened or closed as desired, and at the end of this cock-body, or a tube projecting forward therefrom, is secured a nozzle or tip S. This nozzle or tip is drawn out so that it has a small, tine perforation at the point, and in front of this perforation is extended the thin, sharpen ed point of a linger S) that is attached to the outside of the nozzle.

A tube l0 leads from the lower chamber near the top to nea-r the top of the upper chamber to provide a duet from the air-receiver to the liquid-tank, and this tube is curved from one to the other to provide a connection or brace for the handle, and its upper end leads to the top of the liquid-chamber near the center.

The handle is formed of a cylindrical tube ll, of approxiinatel)7 the length of the shell of the sprayer. This handle-tube near its upper end is connected with the curved tube leading' from the air-receiver to the liquidtank, and at the lower end is connected with a duct that leads from the interior of the handle-tube to the interior of the air-receiver. In this duct is located a cock l2, that can be turned to stop the passage from the interior IOO of the handle-tube to the air receiver or opened to permit free passage therethrough, and in this duct is also located a check-valve. This check-valve is preferably formed byiitting a ball 13 in the end of the duct so that it will shut closely against a seat and stop the passage in a direction away from the air-receiver, the ball being held in place by a tube la, that is screwed into the end of the duct, which holding-tube has its ends slotted, so that when the ball is lying` against the end of the tube, air can pass through the slots into the air-receiver.

A small step or extension 15 is attached to the end of the handle-tube to provide a rest or foot that will bear upon the surface upon which the utensil is placed.

In the handle-tube is fitted a piston 1G, which piston is connected with a rod 17, that extends through the cap 1S on the top of the handle-tube, and is provided with a handle 19 outside. This piston is formed of a cupshaped leather, opening downward and held between a nut and rm plate or disk on the upper side and a nut and plate with spring'- fingers on the lower side.

After a sufficient quantity of the desired liquid has been poured into the liquid-tank through the opening in the top, the cap is screwed in place, the cock '7, which it bears, is closed, and the cock .l2 in the duct leading from the bottom of the handle-tube to the airreceivcr is opened. lVith the cocks in this position, upon working the handle 19 on the end of the piston-rod up and down, the piston is reciprocated in the tubular handle of the utensil in such manner asto force air into the air-receiver, the ball check-valve of course allowing the air to enter but not t0 escape'. lVhen sufficient pressure is generated in the air-chamber by means of the pump, the cock 12 is closed. This pressure is of course eX- erted through the tube connecting the receiver and the tank on the liquid, and when the cock 7 is open, the effect of this is to force the liquid slowly but powerfully out through the outlet tube, cap, and nozzle in a very iine spray.

This construction provides a simple, cheap, and convenient sprayer that can be operated and used by any one, as by tobacco-packers for spraying dry leaves before handling, by florists for spraying flowers or plants, by tailors for spraying cloth, or by launderers for spraying clothes. The utensil occupies but little room. It is of such construction that it is strong and will stand considerable pressure. It can be used after one pumping to give the desired pressure for considerable time, on account of the location and arrangement of the parts and the pressure that can be generated. All of the liquid in the tank can be sprayed out, for the outlet-tube extends to the lower part of the tank near the edge, so that its end can be immersed in the liquid until the last has been blown out, and the device will be durable, for all of the liquid can be blown out, so that the material will not rustor corrode.

I claim as my inventionl. A sprayer consisting of a cylindrical shell formed with a lowerlarger air-chamber and an upper smaller liquid-chamber, the said chambers being connected by a tube that leads from near the top of the air-chamber to near the top of the liquid-chamber, the liquidchamber having an opening in the top, with a perforated cap iitting the opening and provided with an outlet-tube that extends to the lower edge of the liquid-chamber, said cap also being provided with a stop-cock and a sprayingnozzle, a cylindrical handle-tube connected with a duct leading to the air-eham ber, a cock and a check-valve located in said duct, and a piston fitting said handle-tube and provided with an operating-rod having a handle outside of the tube, substantially as specified.

2. A sprayer consisting of a cylindrical shell formed with crowned ends, a smaller cylindrical shell of the same diameter secured to one end of the larger shell, a perforated cap secured to an opening in the top of the smaller shell, said cap being provided with a tube that extends into the smaller shell to near the top edge of the larger shell, a stop-cock and a nozzle with a fine perforation and a spraying-finger extending beyond, a cylindrical handle-tube connected with a duct leading into the larger chamber, a cock and a ball check-valve located in said duct, a piston iitting said handle-tube and provided with an operating-rod having a handle outside of the tube, and a tube leading from near the top of the larger shell t0 near the center of the top of the smaller shell, said tube being connected to each of the shells and also to vdie handle-tube, substantially as specified.
